Simulant Name: UCF/DSI CM Carbonaceous Chondrite Simulant (UCF/DSI-CM-2)
Current Status: Currently Available
Developed By: UCF & Deep Space Industries
Available From: CLASS Exolith Lab
Spec Sheet: CM Spec Sheet
Publications: Britt et al., Simulated asteroid materials based on carbonaceous chondrite mineralogies, manuscript in preparation

The UCF/DSI CM Carbonaceous Chondrite Simulant is a general purpose asteroid regolith simulant based on the Murchison CM carbonaceous chondrite.

To produce the simulant, individual mineral components are sourced and prepared, then mixed together with water and sodium metasilicate that acts as a binder. The resulting mixture is dried to remove the water, then mechanically ground in a rock crusher to achieve the desired particle size distribution.

The simulant is being produced as part of a NASA SBIR grant to create realistic asteroid simulants, and is available from the CLASS Exolith Lab.
